Transfer to Apple M1 Xcode shows an error "'FirebaseCore/FirebaseCore.h' file not found" and "Could not build Objective-C module 'Firebase'"

[Putilov (Stanislav Putilov)]

There is a fairly common problem in my Xcode project. I'm using Firebase and project perfectly works with Xcode 11 on Intel i5, but with Xcode 13 (Swift 5) on Apple M1 there are 2 dramatic errors:

• 'FirebaseCore/FirebaseCore.h' file not found

• Could not build Objective-C module 'Firebase'

So, what I tried:

1. Quite xcode Delete "ProjectName.xcworkspace", "Podfile.lock" and "Pods". Delete project's temp files located at ~/Library/Developer/Xcode/DerivedData (Command + Shift + G in finder) Run "pod install" from terminal. Open "ProjectName.xcworkspace".

Error: Could not build Objective-C module 'Firebase' with Swift 5

2. Adding arm64 to Excluded Architectures for the main project AND for the Pods project

Xcode 12: build Error on FIRAnalyticsConnector

And many other options. But neither one is suitable for me. What should I try?
